It's safe, except when the exchange goes bankrupt, gets hacked, or an exchange employee steals the coins, or they lose the coins for whatever reason. All of the above have happened at various exchanges at various times.
OTOH how good are you at keeping your computer secure, and storing the passphrase securely for a long time?..
Thanks for the detailed and fast responses Maol and Larsfloe: All the systems seem to be very clever thinking on the blockchain...bit over my head, or at least, I try not to go too deep down the rabbit holes (although do like to know what I am investing in!).
OK I will take a look at the handbook.
30x duplicate sounds like a lot...although secure, is that very efficient for resources?
@damoon hay mate, im new to the mining gig too.
We're a bit late to the game but beter late then never, i think Sia's a good a coin to mine, just my opinion.
I have 2 1080ti's getting 3200 Mh/s on one and around 2800 Mh/s on the other becuse the PSU is smaller i had to reduce power and under clock to get stable.
Runing 1 card each on 2 PC's.
You could start mining now on the PC you have, just download the marlin miner, replace the exsiting address with your own and booooom off to the moon.
Im hoping that Sia releases more info on the new ASICS chips preorders start in 5 days.
We really need more info.
I finally writen the backup program on GitHub, it an alpha but it should work (I have just made couple of small tests at the moment).
So I would to share it, I past the link on this post : https://github.com/0xlouis/SIA-Chunk-Backup
Yes, I deleted the folder, then quit Sia and rebooted. I ran several disk utilities programs and disk cleaners and rebooted again. I disabled the time machine local backups and rebooted. The space switched in-between sometimes from deletable to fully occupied, resulting in a slow system etc. Finally after doing the secureErase and disabling the time machine completely + rebooting the space was free.
